Ocaml bindings to taglib

This library provides a set/get interface for several audio file format's tags informations.

Usage is quite simple. All functions using a file type variable, except close_file, may raise Closed if given file was closed.

Types

type t

type file_type =

`\|`	`Mpeg`
`\|`	`OggVorbis`
`\|`	`Flac`
`\|`	`Mpc`
`\|`	`OggFlac`
`\|`	`WavPack`
`\|`	`Speex`
`\|`	`TrueAudio`
`\|`	`Mp4`
`\|`	`Asf`

Supported file types. Warning, types: WavPack, Speex and TrueAudio are only supported in Taglib >= 1.5. Types: Mp4, Asf are only supported with Taglib >= 1.6.

val version : string

Library's version.

exception Closed

File interface

val open_file : ?file_type:file_type -> string -> t

Open a file.

Raises Not_found if file does not exist or could not be opened.

Raises Not_implemented if using a file_type that is not implemented in the system's taglib library.
